METHOD OF ROILILING INTERLOCKIING SHEET-FILING.

To all whom it may concern:-

.Be it known that I, EDWIN E. SLICK, of

Pittsburg, Allegheny county, Pennsylvania, have invented anew and useful Method of Rollin Interlocking Sheet-Piling, of which the to owin is a full, clear, and exact description, re erence being had-to the accom planying drawings, forming part of this speci-- cation, in which- Figure 1 is a 'front elevation showing the.

roughing roll passes; and Fig. '2 is a similar view showing'the succeeding passes, arranged for carrying'out rn y'improved process.

My inventionrelates to the rollingof irregular shapes suitable for interlocking with each other to form sheet piling.

I The object of the invention is to provide a new and im roved method whereby one or. morebroad flanges may be formed at one or both ends of theshape, and such flange or flanges bent into such form that the shapes,

bloom is rolled with its central plane at an angle to the axes of the rolls. This is for the purpose of widening the flanges to the degree which is necessary or desirable where they are to be bent to inclose and interlock with a ortion of the next shape. In order to obtain this result I have found that it is not only important toroll the shape on an angle, but also to bend the flanges to an outward or obtuse angle relative to the web, this angle being greater than 90 degrees. Thus, it will be noted that in passes b, c, d and e the flange portions 5 and 6 extend at obtuse angles to the Web portion 7. In the succeeding passes the flanges are made thinner and of greater width, while maintaining themat the obtuse angle to the web. The web is preferably always rolled at an angle to the axes 0f the rolls, though one or more passes might be inter osed without this feature.

In Fig. 2 I s ow two sets of passes f, g, h,

and f g, h, which are similar to each other.

The pass 9 or g is on a diflerent level from the other two passes the same series, the rolls.

rotating constantly in the'samedirectionin this case. The blank coming fromjthe' ass '6 is passed through one-50f the sets of t ee passes. The'passes g and g are the final reucing asses, in' either of which the blank is broug t toits final sha e, having the wide flan es =5 and 6, the weli 7, and theshort hea flan es .8 and 9. In the final pass h or h the flanges 5 and 6 are curved so as to extend past a plane through the center of the groove at rightangles to the plane of the web. I thus form a shape in which the curved flanges are partially inclosed and 1nterlock with the head flanges 8 and 9 of the next shape, in. accordance with the construc-v tion shown in Patent No.639,885l, granted to Samuel K. Behrend, on December 26,

It will-be noted that in the successive reducing passes either wide flange after passing througha live groove is within a dead groove in the next pass; that is, in each pass, one flange is within the live groove and the other within the dead groove, the flanges being reversed in this regard in the successive asses. Byso alternating the'position of the anges each flange is widened while passing through the live groove, the flanges widening alternately. I

The advantages of my invention result first from the rolling of a flange or flanges of suflicient width so that they may be bent around in such form as to interlock with the next shape and second, from the bending of such flanges past the plane at right angles to the plane of the web, so as to bring them to a position where they will interlock with and hold the flange of the next shape.

'I'have found in practice that the rolling ofthe shape at an angle and the bending of the flanges to an outward obtuse angle of more than degrees to the web, are important features in obtaining the desired width of flange, though the wide flanges may be rolled in other ways; and my broader claims are not limited to this method' The shape maybe rolled with only one wide flange at one or both edges instead of with a two wide flanges at ope edge as shown, said flange or flanges being bent to interlocking position; the rolling maybe carried outin twohigh .rnill s, or any other suitable type of rolling mill; and many other changes may be made in the form and shape of the. section and themethod qfrolling, without departing from my invention.
